Established in 1986, Buffalo Bayou Partnership (BBP) is the non-profit organization transforming and revitalizing Buffalo Bayou, Houston's most significant natural resource. BBP's geographic focus is the 10-square mile stretch of Buffalo Bayou from Shepherd Drive to the Port of Houston Turning Basin. Thanks to the generous support of foundations, corporations, individuals and government agencies, BBP has raised and leveraged more than $150 million for the redevelopment and stewardship of the waterfront - spearheading award-winning projects such as Sabine Promenade and Sesquicentennial Park, protecting land for future parks, constructing hike and bike trails, and operating comprehensive clean-up and maintenance programs. In 2015, BBP completed the $58 million Buffalo Bayou Park project that includes major destinations, natural landscaping, footpaths, trail lighting, water features and pedestrian bridges. Buffalo Bayou Partnership maintains and operates Buffalo Bayou Park, with annual funding provided by the Downtown Tax Increment Reinvestment Zone (TIRZ) #3. Buffalo Bayou Partnership also seeks ways to activate Buffalo Bayou through pedestrian, boating and biking amenities; volunteer activities; permanent and temporary art installations; and wide-ranging tours and events that attract thousands.

Clean Oceans International (COI) is a California-based 501(c)(3) nonprofit working to reduce ocean plastic pollution through science, community engagement, and practical solutions. Our work focuses on two complementary approaches: Community Science & Data (EPAP) Through our Environmental Plastic Assessment Program (EPAP), we train volunteers, students, and partner organizations to measure plastic pollution on coastlines using standardized survey methods. This work generates consistent, comparable data that helps communities understand pollution trends, evaluate cleanup efforts, and advocate for informed solutions. Developing Practical Waste Solutions (PPWC) COI is actively developing small-scale plastic waste conversion systems designed for communities with limited waste infrastructure. This work is currently in the research and development phase, with the goal of creating a safe, adaptable, and deployable system. We are collaborating with partners in places such as Ulithi Atoll and Baghdad, where local teams are currently conducting plastic assessments and cleanups to better understand their waste streams and inform future system design and potential deployment. From Data to Action COI connects field data with on-the-ground action—supporting coastal cleanups, long-term beach adoption efforts, and partnerships that turn information into impact. By combining measurement, education, and implementation, we help communities move from awareness to informed decision-making.

We clean water for kids. We believe that every child deserves to have clean water, clean hands, clean toilets, and access to menstrual health support.
